Answers on a postcard for this one, please.
Newcastle United youngster Sammy Ameobi—an enjoyable social media presence, for those who follow him—posted this picture on Instagram (and Twitter) on Sunday afternoon, along with the caption "Me and Paul Dummett #roomie".
Cartoon aficionados will need no reminding that Ameobi is dressed up as Leonardo, leader of the Teenage Mutant Ninja Turtles, while Dummett appears to have gone as Craig David from the British television show Bo' Selecta!
Yes, Newcastle's fancy dress-themed Christmas party was taking place on Sunday. Either way, this is one of the greatest selfie faces we've ever seen.
Ameobi added further pictures to his Instagram account, hinting at the full glory of some of the costumes being employed.
Ameobi still wins it for us, though.
